Raspberry Pi Revision identification

[recantha2]

I've done a few searches about this on the Forum, but to no avail.

Over on the Milton Keynes Raspberry Jam forum, we've been trying to figure out what the revision numbers reported from /proc/cpuinfo mean.

So far we've worked out the following list:
'0002' => 'Model B Revision 1.0',
'0003' => 'Model B Revision 1.0 + Fuses mod and D14 removed',
'0004' => 'Model B Revision 2.0 256MB',
'0005' => 'Model B Revision 2.0 256MB',
'0006' => 'Model B Revision 2.0 256MB',
'0008' => 'Model A 256MB',
'000f' => 'Model B Revision 2.0 512MB',

This ties up with some great work that Frank Carver's done over on RaspberryAlphaOmega (http://raspberryalphaomega.org.uk/?p=428).

Our big, geeky question is... What are the differences between 04, 05 and 06? Does it have something to do with manufacturing country, or perhaps when the boards were manufactured? We'd love to know!

Hi,
can't answer your question, but add this to the list :

'000e' => 'Model B, Revision 2.0, 512MB'

Jamesh can probably answer your question, and the history of the '000e' revision.

There are three manufacturers of the boards, and they have unique board revs:

'0002' => 'Model B Revision 1.0',
'0003' => 'Model B Revision 1.0 + Fuses mod and D14 removed',
'0004' => 'Model B Revision 2.0 256MB', (Sony)
'0005' => 'Model B Revision 2.0 256MB', (Qisda)
'0006' => 'Model B Revision 2.0 256MB', (Egoman)
'0007' => 'Model A Revision 2.0 256MB', (Egoman)
'0008' => 'Model A Revision 2.0 256MB', (Sony)
'0009' => 'Model A Revision 2.0 256MB', (Qisda)
'000d' => 'Model B Revision 2.0 512MB', (Egoman)
'000e' => 'Model B Revision 2.0 512MB', (Sony)
'000f' => 'Model B Revision 2.0 512MB', (Qisda)

Thanks Dom, I'll update my blog article in line with this.

Thanks, Dom!

Out of interest, who made the 02 and 03s? I know I should know this...

[metachris]

I just wrote up a little Python script to display model and maker, and thought I'd share it here: https://github.com/metachris/raspberryp ... etector.py

I *think* Egoman made the first production boards.

[andrevs]

Can one derive the boards colour from the revision? I mean, are all egoman boards red? I doubt so as the red boards were only recently announced and the list mentions 256 MB egoman b2 pis.
So, if egoman makes both colours, do they share the same revision or can one tell them apart by the revision?

'000e' => 'Model B Revision 2.0 512MB', (Sony)
'000f' => 'Model B Revision 2.0 512MB', (Qisda)

Does Qisda manufacture in the UK? I have two revision 000f boards, both labelled "Made in the UK."

[metachris]

Anyone knows who manufactured '0002' and '0003'? Perhaps we could also collect more infos about differences in the gpio numbering scheme, etc.

In case anyone is interested - I've updated the rpi_detect_model.py script to make the specific attributes more easily accessible.

I too have a 000f "Made in the UK".

[jojopi]

I too have a 000f "Made in the UK".

And me. In my case, I remember that on original firmware when it was new it reported 0005. So I hypothesize that Sony initially incremented revision from 0004 to 0005 when moving from 256MiB to 512MiB. According to dom's official numbers, that is wrong on two counts. The newer firmware corrects from 0005 to 000f when it detects the larger RAM, but has no way of knowing it is a Sony not a Qisda. (Except perhaps that Sony are known to have made this mistake and Qisda might not be, so 0005 to 000e might have been better.)

The firmware does not appear to allow "program_board_rev=14" when already 15, so we may be stuck with this.

[larsth]

On my Raspberry Pi 3B this command:

Code: Select all

cat /proc/cmdline | awk -v RS=" " -F= '/boardrev/ { print $2 }'

returns the board rev., which is:

0xa02082

The same value does also exists in /proc/cpuinfo :

Code: Select all

cat /proc/cpuinfo | grep Revision

returns:

Revision : a02082

Is that really the board rev. number for a Raspberry Pi 3B?

Edit:
Looking at the content from other Raspberry Pi /proc/cpuinfo files that looks like something else, fx. the firmware rev.

From the Pi2 onwards the system has changed.
There is more information encoded in the revision number (processor, RAM, manufacturer, etc).

See e.g. https://github.com/AndrewFromMelbourne/ ... i_revision for more information
